Due to their aesthetic, sustainable, durable, and resistant qualities, stone materials have accompanied the disciplines of architecture and engineering since their origins. As is known, in Mexico, stone has been a fundamental element in pre-Hispanic constructions where experimentation was done with vaults, ashlars, masonry, etc.
Rammed earth has been used in construction for thousands of years, with evidence of its use dating as far back as the Neolithic Period. Commonly used especially in China, the technique was applied to both ancient monuments and vernacular architecture, with the Great Wall utilizing the technique. Though interest in rammed earth declined in the 20th century, some continue to advocate its use today, citing its sustainability in comparison to more modern construction methods. Most notably, rammed earth structures use local materials, meaning they have low embodied energy and produce little waste. Below, we describe how to build with this material.
How can we transport ourselves to natural environments when we are in completely urban situations? The materiality of our surroundings is an important factor that determines the atmosphere we inhabit. In many cases, the use of natural materials in interior architecture can help evoke nature in our daily spaces. In this article, we will specifically analyze the effect that cork has as a special resource in the design of interior spaces. Cork is the bark of a tree species called cork oak. When extracted from the tree, it is transformed into a useful raw product and can be applied to a variety of different uses.
In addition to their aesthetic appeal, the use of raw materials can save resources by bypassing the use of additional coatings and processes. This type of solution was most commonly used in utility buildings, such as infrastructure, factories, and warehouses. Exposed concrete floors, for example, were primarily found in industrial spaces, parking lots, and gas stations. However, they are increasingly being used in structures of different programs due to their appearance, durability, resistance, and vast possibilities for finishes. But what are the main factors to be aware of when using a concrete floor for a project?
In recent years, much attention has been given to timber constructions. Being a sustainable and renewable material, which captures a huge amount of carbon during its growth, the innovations related to this material have allowed for increasingly higher constructions. However, when we talk about wood we approach an immense variety of species, with different strengths, nuances, potentials, limitations and recommended uses. While there are extremely hard and heavy woods, with strengths comparable to concrete, there are other soft and soft woods that are suitable for other purposes.
The history of architecture shows that the use of raw materials has always been somewhat common, whether in ancient vernacular techniques or within the Brutalist movement, to name a few. It is evident that the language of a project is often linked to its material, as various sensations and the perception of space are directed by the aesthetic and physical quality of the given element. For this reason, we have gathered ten buildings that highlight the quality of their materials, whether to make a statement, reinterpret a technique from the past, or to re-signify the potency of some of these elements.
As cliché as it may sound, there are two things that architects really like: exposed concrete and the color black. While concrete offers a distinctive rough aesthetic, emphasizing the tones, textures, and surfaces that shape the concrete mixture, the sobriety that the color black provides allows the architect to highlight specific characteristics precisely. Combining the two seems natural. But black pigmented concrete is not as common as we might imagine. Below we talk a little about the black concrete production process and some projects that use it.
Hemp is one of the oldest crops domesticated by humans. With its wide variety of uses and applications, it’s easy to understand why it’s been a desirable product throughout history. Hemp seeds and flowers are used in health foods, medicines, and organic beauty products; the fibers and stalks of the hemp plant are used in clothing, paper, and biofuel. Today even a waste product of hemp fiber processing, so-called hemp shives, is being utilized to create sustainable building materials like hempcrete.
Hempcrete is a bio-aggregate concrete, where the hemp shives - small pieces of wood from the stalk of the plant - are mixed with either a lime or mud cement to create a durable, eco-friendly building material. Hempcrete is lightweight and non-structural, but can instead be integrated with traditional building construction systems. Similar to traditional concrete, it can be either cast-in-place or prefabricated into building components like blocks or sheets.
Keeping the materials in their natural and raw form in the projects seems to be more and more popular in contemporary architecture. The modern style legacy of keeping the construction elements visible not only establishes a frank relationship between the user and the built environment but also allows for a more diverse material palette and can be a very important tool when designing interiors. Brick is perhaps the most popular material in this context. Nowadays, people use the term exposed brick "finishing", which gives the concept of exposed materials a whole new meaning, namely ornamental, sometimes even replicated as wallpaper or merely decorative tiles.
Peter Zumthor, in one of his most emblematic works, gives concrete an almost sacred dimension. The work in question is the small Bruder Klaus Field Chapel, located in a small village in Germany, a construction that is both robust and sensitive. Built with white cement, which was mixed with stones and sand from the region, the chapel is composed of 24 layers of concrete that were poured day after day by local labor, and compressed in an unusual way. The building's flat and smooth exterior contrasts with its interior, which was initially made of inclined wooden logs forming a triangular void. To remove these internal forms, the logs were set on fire in a controlled process, reducing them to ash and creating a carbonized interior that varied between black and gray and retained the texture of the negatives of the logs. The result is a masterpiece of architecture, a space for reflection and transformation, in which the same material appears in diametrically opposing ways.
The world of architecture and construction has observed, with increasing attention, technological innovations involving wood. Although it is a material that has been widely used for thousands of years, recent research involving industrial manufacturing and machining technologies has provided even greater quality control and an increased diversity of uses, causing it to be described by many as the material of the future. To this end, common myths including wood's lack of resistance to fire and the implausibility of using it to structure tall buildings have been debunked.

Craftmanship is back. Following a century of mass production and industrial development, crafts are starting to be revalued and reinterpreted. A new sensitivity towards raw materials, the recovery of local techniques and the defense of small-scale trade are a few of the claims that this comeback represents. Materials such as earth and ceramics, textiles and wood are being reinterpreted by designers, artists, and architects around the world, in search of both their own style and the representation of collective nostalgia.
Kengo Kuma's architecture can be defined by its respect to Japanese constructive traditions and alignment with its context. Internationally recognized, the architect is known mainly for his wooden (or mixed) structures, which arise from a simple pattern of assembly and, which through different intersections and angles, generate a complex whole. The representations created by his team bring very specific details, ranging from didactic isometrics to complex parametric drawings. We have gathered details of five inspiring projects by Kengo Kuma that use wood.
Mass timber has been hailed as the solution to architecture’s notorious sustainability problem – that buildings account for nearly 40% of global energy use is by now a worn and overcited fact. But timber isn’t the world’s only renewable material, and architects and engineers have begun looking elsewhere for other possible steel and concrete replacements. One such possibility that has recently come to light is engineered or laminated bamboo, a highly sustainable and structurally impressive material. Below, we investigate how laminated bamboo is made, what its primary qualities are, and how it compares to timber.
Is wood the future of construction?
Newton’s Third Law of Motion dictates that for every action, there is an equal and opposite reaction. In urbanism, this concept is evident in how the unprecedented growth of the built environment causes a reaction in rural landscapes. By 2050, the number of people living in cities will have increased by 2.5 billion, representing two-thirds of the global population. This mass flow of people from rural to urban areas gives rise to an equally dramatic flow of natural resources. As can be seen in studies such as Tom Hegen’s The Quarry Series, whose imagery accompanies this article, the extraction of these minerals represents yet another physical manifestation of rapid, linear urbanism.
Rotation, displacement, and interleaving of blocks are some of the options that enable the diversity of raw brick patterns in architecture. The shape of these elements, usually used for the construction of walls, has been explored in a creative way to compose facades of residential buildings, representing the formal identity of the building itself and its relationship with its context.
The historic village of Indein, Myanmar was founded by monks around the 3rd century B.C, who wanted to spread Buddhism across the country. Hundreds of pagodas, ornaments, and statues of Buddha were built around the area, but with time, the village was abandoned and its temples were consumed with greenery. Nowadays, the site stands as a visual contradiction of old and new, as people have begun renovating and preserving the historic structures little by little, surrounding the crumbling temples with brand new white stupas.
